Hi, I want to filter when there is no 'ts' or 'exp' object.

Table Config : 
"ingestionConfig": {
  "filterConfig": {
    "filterFunction": "Groovy({ ts == null || ts < 1000000000 || exp == null}, exp, ts)"
  }
}

Table Schema : 
{
  "name": "exp_utc",
  "dataType": "LONG",
  "transformFunction": "exp*1000",
  "format": "1:MILLISECONDS:EPOCH",
  "granularity": "1:MILLISECONDS"
},
{
  "name": "exp_asia_seoul_datetime",
  "dataType": "STRING",
  "transformFunction": "toDateTime((exp*1000)+(timezoneHour('Asia/Seoul')*3600000), 'yyyy-MM-dd HH:mm:ss')",
  "format": "1:SECONDS:EPOCH",
  "granularity": "1:SECONDS"
}

Normal collection data :
{"id":"E8DB","tp":1,"fw":"1.5.0","vc":22,"ts":1661175231,"ri":-59,"ad":3,"exp":1678450474,"ar":{},"mg":{"1":0.2,"2":0.2,"3":0.2}}

filter data :
{"id":"240A","tp":1,"fw":{"1":{"1":-25,"2":-10,"3":-4}},"ar":{"0":1},"mg":{"1":0.2,"2":0.2,"3":0.2}}

The following error occurs because the 'exp' filter does not work.

Caused by: java.lang.RuntimeException: Caught exception while executing function: plus(times(exp,'1000'),times(timezoneHour('Asia/Seoul'),'3600000'))

Any problem with this filterFunction?

"filterFunction": "Groovy({ ts == null || ts < 1000000000 || exp == null}, exp, ts)"
